Stephen's A8 Blog > Double Rainbow - meh! I've got Quad Rainbow pt.6

Posted 05 December 2011

I usually don't post a video of something that is not working, but oh well - it's been a while, and I was finally able to put in some time. The ball (missle 3 to be precise) motion is done in the Immediate VBI. It's not working 100% just yet, but masking works, and the motion mostly...

Stephen's A8 Blog > Term80 Disassembly

Posted 07 November 2011

This is a very early work in progress. I hope to have some more time to work on this towards the end of December. I may wait to work on it until after I receive my Turbo Freezer though.

Here you see the before image. I am running MS BASIC-80 Ver 5.21 on top of CP/M 2.22. This is running...

Stephen's A8 Blog > Double Rainbow - meh! I've got Quad Rainbow pt.5

Posted 18 July 2011

Starting to take shape now - here's hopefully the final video with static background. I am still experimenting to see how much data I can throw at the screen during VBI and still maintain 60FPS. I am going to have to scale the video RAM way down from where it is currently, as 2048 bytes is too much :( I initially planned for 1024, this should...
